Generation of excel report from jasper 3.7.5 report

[matanmi]

Microsft Office Excel cannot access the file http://localhost:8080/legend2.net/Servlets/xls.

On my Jboss the errors are

Hi,

 

I think you need to look closer into the /demo/samples/webapp sample shipped with the JR project distribution package, to see what the XLS servlet needs to work properly. You probably did not put the generated JasperPrint object at the correct location on the HTTP session, as the servlet expects it.

 

I hope this helps.
